Chicago-latrobe 53438 Cobalt Reduced Shank Drill Bit 19/32 in

Product Description

The CHICAGO-LATROBE 53438 is a cobalt reduced shank drill bit designed for demanding metal drilling applications in portable and stationary setups. With a 19/32-inch (0.5938 inch) cutting diameter and a 1/2-inch straight-cylindrical shank, this bit fits standard 1/2-inch chuck equipment even though the cutting end is larger. The 118-degree split point starts on contact without a center punch and reduces walking on hard surfaces. Cobalt construction handles heat buildup better than standard high-speed steel, making it a dependable choice when drilling through tough ferrous metals.

The 53438 is suited for portable drilling operations on cast iron, steel, alloy steel, and carbon steel workpieces in fabrication shops, maintenance environments, and industrial job sites. The Series 190C design covers general-purpose drilling where a reduced shank allows a larger-diameter bit to run in a 1/2-inch chuck. Licensed electricians, millwrights, pipefitters, and general maintenance mechanics commonly reach for this type of bit when drilling oversized holes without switching to a larger drill press setup.

Key Features

• Cobalt tool material provides increased heat and wear resistance compared to standard HSS bits
• 118-degree split point reduces thrust and eliminates center-punch requirements on most metals
• Reduced shank design (1/2-inch shank, 19/32-inch cutting diameter) allows use in standard 1/2-inch chucks
• Right-hand spiral flute with regular helix for consistent chip evacuation
• 2-flute configuration with 3-1/8-inch flute length handles moderate hole depths
• General-purpose performance rating covers a wide range of ferrous workpiece materials

Compatibility

Designed as an OEM-style general-purpose replacement or direct-use cobalt drill bit compatible with any 1/2-inch keyed or keyless drill chuck in portable or bench-mounted drilling equipment. Primary workpiece materials are cast iron and steel; secondary materials include alloy steel, carbon steel, and cast iron.

Installation Notes

Install in a 1/2-inch chuck and tighten securely before operation. Secure the workpiece with a vise or clamps before drilling to prevent rotation and injury. Apply cutting fluid or coolant to extend bit life when drilling through hard alloy steels, even though the bit is rated for dry use. Inspect the cutting edges before each use and replace or resharpen if chipping or dullness is observed to maintain hole-diameter tolerance.
